ARRANGEMENT OF THE OPERATING CAMS OF THE FUEL VALVES" IN DIESET MOTORSApplication filed April 20, 1922. Serial No. 2355,6612}.

To aZZ whom it may concern:

Be it known that I, ALFRED RnINsoH, a subject of the State of BavariaGermany, residing at Berlin-v larienfelde, Prussia, Germany, 11Hranitzkystrasse, have invented certain new and useful Improvements inthe Arrangement of the Operating Cams of the Fuel Valves in DieselMotors, of which the following is a specification.

In the construction of Diesel-motors the fuel feed valves are usuallyarranged in the plane of the center axis of the cylinders, so

' each other.

that the two fuel feed valves of a cylinder block have a rather greatdistance from The operating cams for the fuel feed valves are disposedon the operating shaft in the same planes, in which the fuel valves arearranged and accordingly also have a rather great distance from eachother. On account of this construction it is necessary to provideseparate arrangements for the adjustment of the needle stroke of thefuel feed valves.

According to the invention the before described construction issimplified thereby, that the operating cams for the two fuel feed valvesof a cylinder block are arranged closely. abreast of each other on theoperating shaft between the vertical planes of said valves. On accountof this arrangement it is possible to employ a common needle strokeadjusting device for both valves whereby a saving of space and weight isobtained. i

In the drawing, which represents one form of construction of the presentinvention.

Fig. 1 shows diagrammatically a front view of a Diesel-motor equippedwith the improved arrangement.

.Fi g. 2 is a plan view and Fig. 8 is a side view of the same. I

The two fuel feed valvesware disposed as usually in the planes of .thecenter axis of.

the cylinders. The appropriate operating cams a and 6 however arenotdisposed in the manner usual until now, on the operating shaft belowsaid fuel valves, but.

are arranged on this shaft 0. between the vertical planes of said fuelfeed valves a and b in closeproximity to each other. The transmission ofthe strokeof-saidcams to the fuel feed valves is effected by means ofrod lever arrangement cl, f, 9..

Having thus particularly described the nature of my invention, what Iclaim asnew and desire to secure by Letters Patent ofthe United Statesis:

1. In'an internal combustion. engine of the Diesel type, the combinationof a plurality of upright cylinders, fuel feed valves for said cylinderslocated in registrywith the vertical axes thereof and in line with eachother, "a horizontal cam-shaft extending parallel to the plane passingthrough the axes of the cylinders, operating cams on said shaft in closeproximity to'each other between the parallel vertical planes which passthrough the axes of the cylinders and are perpendicular to-the cam-shaftand transmission means whereby said cams are operatively connected withsaid valves.

2. In an internal combustion engine of the Diesel typefthe combinationof a' plur rality of upright cylinders, fuel feed valves forsaidcyliiiders located in registry with the vertical axes thereof and inline with each other, a horizontal cam-shaft extending parallel. to theplane passing through the axes of the cylinders,operating cams on saidshaft in close proximity to each other between the parallel verticalplanes which pass through the axes of the cylin- 7' ders and areperpendicular to the cam-shaft,

vertical rods in registry with said cams and adapted to be operatedthereby, bell-crank levers pivotally connected with said rods i andcranks journalled on said engine between said valves and extendmg towardeach other, said cranks having one member in registry with one member ofeach bellcrank andthe other connected with one of said valves wherebythe latter are operated 5 by said cams. I

In" testimony whereof Iaffix my signa ture in presence of two witnesses.
